Int. Cl. D0111 /00 US. Cl. 57-36 2 Claims ABSTRACT OF THE DISCLOSURE An enclosure is provided positioned remote from a spinning frame and a source of textile slivers for receiving air under controlled conditions of temperature and humidity. The enclosure confines the air against dispersion into the ambient areas as would create unpleasant conditions for personnel working with the equipment. The slivers are exposed to the conditions prevailing within the enclosure thus, conditioning the slivers to a predetermined moisture content prior to introducing the slivers into the drafting system of a spinning frame.

This invention relates to the direct spinning of textile slivers into textile yarn, and more particularly to an improvement facilitating the conditioning of the yarn to a predetermined moisture content for spinning, while avoiding unplesant conditions for workers by the use of a remote enclosure.

Heretofore, there have been several improvements seeking to provide means for conditioning slivers as to moisture content prior to spinning. One such improvement has been described in my U.S. Letters Pat. No. 3,070,- 948 entitled Spinning Frames, issued Jan. 1, 1963. The difficulty with such a system centers about the undesirable working conditions prevailing on the upper floor where conditioning takes place. The system contemplates creeling in a room superposed upon a room containing the spinning equipment and simply guiding the strands downwardly through the floor separating the rooms to the drafting system of the spinning frames below. Such contemplates conditioning the yarn as to moisture content in the upper room. Extremes of temperature and humidity are required for such procedure, and it has been found that such conditions are uncomfortable for workers. U.S. Letters Pat. No. 3,247,551 in the name of I. R. Whitehurst entitled Apparatus and Method of Conditioning Textile Material Being Drafted, issued Apr. 26, 1966, deals with an attempt to condition slivers in the drafting system of a textile machine. Such presents many almost insurmountable problems, the most significant of which is the loss of ready accessibility to the drafting system. Similar problems are encountered in connection with my US. Letters Pat. No. 3,073,106, entitled Spinning Frames, issued Jan. 15, 1963.

Accordingly, it is an important object of this invention to provide an improved system for conditioning textile slivers as to moisture content prior to introducing same into the drafting system of a spinning frame.

Another important object of the invention is the provision of means 'for conditioning textile slivers as to moisture content, while preserving ready accessibility to the spinning frame.

Another important object of the invention is to effectively condition textile sliver as to moisture content while maintaining reasonable working conditions for personnel in the area.

The construction designed to carry out the invention will be hereinafter described, together with other features thereof.

The invention will be more readily understood from a reading of the following specification and by reference United States Patent 0 to the accompanying drawings forming a part thereof, wherein an example of the invention is shown and where- FIG. 1 is a schematic perspective view illustrating an apparatus and method for spinning yarn in accordance with the invention,

FIG. 2 is a schematic end elevation of a modified form of the invention, and

FIG. 3 is a schematic side elevation illustrating another modified form of my invention.

The drawings illustrate an apparatus for spinning yarn wherein a spinning frame A having a drafting system receives textile slivers from a source B. Means C supply air under controlled conditions of temperature and humidity. An enclosure D is positioned remote from the spinning 'frame and the source of textile slivers receiving the air for confining same against such dispersion as would create unpleasant conditions for workers. Means E are provided for guiding the slivers through the enclosure exposing the slivers to such controlled conditions of temperature and humidity obtaining in the enclosure for conditioning the slivers to a predetermined moisture content, and introducing the conditioned slivers into the drafting system. Thus, direct spinning of slivers is facilitated.

In two of the embodiments illustrated (FIGS. 1 and 3) a first floor is contemplated upon which the spinning frame is situated. A second floor superposed upon the first floor supports the source of textile slivers. The enclosure is positioned essentially below the second floor.

In FIG. 1 the second floor defines an upper portion of the enclosure and includes a partition below the second floor defining a lower portion of the enclosure. Means are provided for dividing the enclosure in segments permitting variable amouts of air to flow between segments. In FIG. 3 the enclosure is an elongated chamber and a plenum is provided communicating therewith. In FIG. 2 sliver cans are positioned beside the spinning frame, and the enclosure is a plenum carried by the spinning frame above the drafting system.

The method contemplates spinning slivers directly into yarn upon a spinning frame having a drafting system. A supply of air is confined under controlled conditions of temperature and humidity remote from the spinning frame and the source of textile slivers against such dispersion as would create unpleasant conditions for workers. The slivers are guided through such confined supply of air exposing the slivers to such controlled conditions of temperature and humidity for conditioning the slivers to a predetermined moisture content. The conditioned slivers are introduced into the drafting system of the spinning frame, whereby direct spinning of slivers is facilitated.

A plurality of spinning frames A are illustrated in FIG. 1 as being positioned upon a first floor 10 of a mill. A source slivers B in the form of sliver cans are illustrated as being positioned upon a second floor 11 super posed upon the first floor 10. The slivers 12 are fed from the sliver cans B and pass through the floor 11. The slivers are then exposed to air under controlled conditions of temperature and humidity from the means C for supplying air. The means C includes a plenum 13 having suitable nozzles 14 for distributing preconditioned air humidifying the room and controlling its temperature.

An enclosure D is defined by the second floor 11 and a partition 15. The enclosure D is thus positioned remote or separate and exteriorly of the spinning frame and the source of textile sliver. Air is received by the enclosure which suitably confines same against such dispersion as would be such as to create unpleasant conditions for workers. The enclosure D is divided into segments, as illustrated at 16 and 17, as by louvers 18 which are provided with suitable means (not shown), but which are preferably automatic and power operated, for varying the amounts of air which flow between the segments. Means E are provided for guiding the slivers through the enclosure D exposing the slivers to the controlled conditions of temperature and pressure subsisting in the enclosure for conditioning the slivers to a predetermined moisture content.

Such guide means include a plurality of spaced sliver tubes 19, sliver guides 20, and additional sliver tubes 21 for introducing the conditioned slivers into the drafting system 22 of the spinning frames A. The sliver guides 20 are disposed within the enclosure D and may be in the form of tubes havin holes so as to render the tube largely porous to the passage of air. Such may also be of helical, spring-like, construction wherein the helix has a large pitch so as to be predominantly open for the passage of air.

A humidity controlled roller is illustrated at 23 for actuating suitable automatic control means (not shown) for controlling temperature and humidity conditions within the enclosure D. A separate humidity and temperature control measuring device 24 is provided with the enclosure D. for exerting control upon the temperature and humidity Within the enclosure D. The humidity measuring device 23 overrides the control 24. Thus, the humidity control roller 23 and the humidity and temperature control thermostat 24 may exert control upon the temperature and humidity conditions contained within the enclosure D responsive to conditions of the sliver.

Referring now to FIG. 2, a modified form of the invention is illustrated wherein the sliver cans B are positioned upon the first floor beside the spinning frames A. The enclosures D are provided in the form of plenums carried by the end frame members 25 of the spinning frame remote from the spinning frame in that they are separate from and mounted exteriorly of the spinning frame and the sliver supply B. The plenums which form the enclosures D have side Walls 26 and 27 and top and bottom walls 28 and 29. Means C supply air under controlled conditions of temperature and humidity to the plenums. Guide means E are similar to those described above. Suitable controls (not shown) for temperature and humidity are provided.

FIG. 3 shows another modified form of the invention wherein like reference characters are used to designate like parts. The enclosures D have means C including a plenum 30 communicating therewith. The enclosures D include elongated chambers 31 which are connected with the plenum 30 through passageways 32. In this embodiment the spinning frames A are positioned upon the bottom floor 10 and the sliver cans B are carried upon the second floor 11. The slivers 12 pass through guide means E from the sliver cans through the second floor 11 thence into the enclosures D and into the drafting system 22 of the spinning frames. Similar humidity and temperature controls as previously described in connection with FIG. 1, but which are not shown in FIG. 3 are provided,

It has, for example, been found that with air heated to 90 Fahrenheit with 70% humidity in the enclosures is suitable for sliver having 20/1 yarn count and imparts humidity thereto.

While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without de-- parting from the spirit or scope of the following claims.
